Full / Hemi Anechoic Chambers

Noise control Solutions

Adams offers full and hemi-anechoic chambers, reverberation chambers, Noise Control Booth, Noise Testing Booths from ECKEL Industries, USA. Over the years, industries such as automotive, aircraft/aerospace, instrumentation, and computer manufactures as well as research organizations, universities, colleges, government, educational and industrial laboratories have relied on Eckel for the design, fabrication, and installation of anechoic chambers, reverberation rooms, modular panel enclosures, audiometric booths, and architectural noise control systems just to name a few.

ECKEL Reverberation rooms are designed for the determination of sound output of noise sources, transmission loss of partition, insertion loss of silencer, response characteristics of microphones and random incidence absorption co-efficient of materials.

ECKEL’s cost effective, efficient Eckoustic Modular Panel (EMP) enclosures and sound barrier walls provide a proven, reliable, long-term solution for obtaining maximum noise reduction and sound isolation in industrial, test and research facilities.

Full/Hemi Anechoic Chambers

Eckel Industries Inc. designs, fabricates and installs full and hemi-anechoic chambers to precise specifications for government laboratories, industrial concerns, and leading universities. Fully integrated systems and designs include requirements such as isolated floors, light and power connections, ventilation, temperature and humidity control, instrumentation sleeves, control supports, working floors, and single and double sound doors. Anechoic Chambers are echo-free enclosures with a sound energy absorption level of 99% to 100%, or a reflected sound pressure level of 10% or less. The frequency at which the energy absorption drops below 99%, or the pressure reflection exceeds 10%, is known as the
low-frequency cut-off.


The anechoic chamber at Orfield laboratory in Minneapolis, MN is NIST certificate and was designed engineered and constructed by Eckel Industries. This chamber is “The quietest place on earth” according to the Guinness Book or World Records 2005. The ambient noise level was measured at -9.4dBA (typical chamber run 15 – 20 dBA).


Totally integrated systems and designs include requirement such as isolated floors, lighting and power connections, ventilations, temperature and humidity control instruments, sleeves, control supports, working floors and single & double acoustic doors.
